Insufficient metering pump accuracy in PCTG extrusion
Problem Phenomenon
Unstable metering pump output causes extrusion fluctuation.
Cause Analysis
Metering pump gear wear, increased clearance, volumetric efficiency decreases.
Solution
Replace or repair the metering pump; regularly calibrate metering pump output.
Key Takeaway
PCTG precision extrusion requires high-precision metering pumps.
